Beauty-treatment method
Abstract
A cosmetic method for obtaining substantial cosmetic effects
through simple massaging by ordinary people by first massaging in
the direction of arterial blood flow and then in the direction of
venous blood flow, or by massaging the surface of the skin with the
use of a cosmetic comprising disintegrating particles while the
pulse, dermal vasculature, skin temperature, or dermal blood flow
is in a stimulated, dilated, elevated, or stimulated state as
opposed to a resting state, and by washing the skin with a cleanser
or a detergent, and then using a skincare cosmetic, wherein
massaging is done using a massaging cosmetic comprising
disintegrating particles before the skincare cosmetic is used after
washing with a cleanser or detergent. This allows effective
skincare to be achieved.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a beauty-treatment method in which
massaging is done in the direction in which the blood flows or
massaging is done while the dermal blood flow is in a stimulated
state as opposed to a resting state, allowing short periods of
massaging to result in considerable massaging effects and thus in
pronounced cosmetic effects related to improved skin color or the
like.
The present invention also relates to a cosmetic method for rapidly
restoring the moisture components of skin which have been washed
away when the skin is washed with a cleanser or a detergent.
2. Description of the Related Art
Beauty soaps and other detergents containing surfactants as their
principal components are commonly used to wash the skin.
Detergents designed to remove soil through the action of
surfactants, while effective in removing perspiration, dirt, dust
and other contaminants from the skin, fail to satisfactorily remove
sebum, cosmetics and other types of oily soil. In particular,
contemporary foundations and other cosmetics are resistant against
perspiration or water and adhere firmly to the skin, and thus
cannot be adequately removed by detergents containing surfactants
as their principal components. Consequently, cleansers consisting
primarily of components for dissolving oily soil, such as liquid
paraffin, squalane, and isopropyl myristate, are used to remove
such oily soil. In such cases, the skin is washed by so-called
double washing, in which oily soil is first washed away with a
cleanser, and aqueous soil is then washed off with a detergent
containing surfactants as its principal components.
Detergents containing both surfactants and components for
dissolving oily soil have been developed recently, making it
possible to remove both oily soil such as foundations and common
soil such as perspiration and dust in a single washing cycle.
Washing the skin with a cleanser and a detergent, however, tends to
remove the sebaceous membrane, intercellular sebum (ceramide), NMF
(natural moisturizing factors), and other moisture components of
the skin along with the soil.
When the sebaceous membrane is removed as a result of washing, it
takes several hours to be regenerated, and no intercellular sebum
or NMF is formed until the corneal layer is formed again. The skin
meanwhile has lower moisture retention capacity, less defensive
capacity against external stimulation, and is less soft.
After the skin has been washed with cleanser or detergents,
skincare has thus been undertaken with the use of skincare
cosmetics such as skin lotions, emulsions, and cremes in order to
enhance the moisture retention capacity of the corneal layer of the
skin, enhance dermal blood flow, promote the regeneration of the
moist components of the skin, and improve skin softness.
However, despite the use of skincare cosmetics, skin tightness or
luster is often lost as a result of changes in physical
constitution, environment, or the like, and tightness or luster is
not readily restored once it is lost.
Massaging is also sometimes attempted to address this, but
massaging is known to cause wrinkling or slackness, depending on
the method used. It is thus usually done by experts such as
beauticians. Experts are entrusted in the direction in which
massaging is done at certain massaging locations, the time needed
for massaging, and the sequence of the massaging locations or the
like. The massages given by experts are difficult for ordinary
people to manage on their own and are hard work, which is rarely
done at home.
Massages are generally done not only after the use of cleansers or
detergents as described above, but also to promote blood
circulation and to obtain the cosmetic effect of providing the skin
with tightness or luster. Massaging is known to cause wrinkling or
slackness, depending on the method used. It is thus usually done by
experts such as beauticians. Experts are entrusted in the direction
in which massaging is done at certain massaging locations, the time
needed for massaging, and the sequence of the massaging locations
or the like. The massages given by experts are difficult for
ordinary people to manage on their own and are hard work, which is
rarely done at home.
Because massaging promotes blood circulation and thus affords a
variety of substantial beneficial effects, however, it would be
desirable if ordinary people were able to manage simple massaging
on their own.
A first object of the present invention is to provide a novel
beauty-treatment method which resolves the aforementioned drawbacks
of the prior art, which can be easily managed by ordinary people,
and which affords considerable massaging effects as well as
pronounced cosmetic effects.
A second object of the present invention is to achieve effective
skincare by incorporating massaging that is easily managed by
ordinary people in a cosmetic method comprising washing the skin
and subsequent skincare.
SUMMARY OF THE INVENTION
To achieve the first of the aforementioned objects, the present
invention provides a beauty-treatment method broadly divided into
first and second methods.
That is, as a first beauty-treatment method, the present invention
provides a beauty-treatment method comprising massaging first in
the direction of arterial blood flow and then massaging in the
direction of venous blood flow.
A specific embodiment of this beauty-treatment method which is
proposed, particularly when the face is the massaging location, is
a beauty-treatment method in which massaging is first done in such
a way as to (a) describe a line from the mouth past the wings of
the nose, followed by any of (b) massaging of the cheeks so as to
describe a circle from the mouth, past the lower eyelids, toward
the ears, (c) massaging of the forehead so as to describe an arc
from between the eyebrows past the upper forehead toward either
end, and (d) massaging of the lower eyelids from the inner corners
of the eyes to the outer corners of the eyes; or a beauty-treatment
method in which the massaging in (b), (c) and (d) is done in any
sequence after the massaging in (a). Of these, a preferred
beauty-treatment method for the face is a beauty-treatment method
in which (a) massaging describing a line from the mouth past the
wings of the nose, (b) massaging of the cheeks so as to describe a
circle from the mouth, past the lower eyelids, toward the ears, and
(c) massaging of the forehead so as to describe an arc from between
the eyebrows past the upper forehead toward either end are done,
two to three times each, in the sequence (a), (b) and (c), two to
three times in succession, and (d) massaging of the lower eyelids
is then done from the inner corners of the eyes to the outer
corners of the eyes two to three times.
Another embodiment that is offered features the use of a cosmetic
when implementing a beauty-treatment method consisting of such
massaging, and in particular features the use of a cosmetic
comprising disintegrating particles and, as needed, a blood
circulation promoter, oil, cosmetic whitener or sebum secretion
inhibitor.
As a second beauty-treatment method, the present invention provides
a beauty-treatment method in which a cosmetic comprising
disintegrating particles is used as a massaging cosmetic, and the
massaging is done when the pulse, dermal vasculature, skin
temperature, or dermal blood flow is in a stimulated, dilated,
elevated, or stimulated state as opposed to a resting state.
The present invention also provides a beauty-treatment method in
which a cosmetic comprising disintegrating particles is used as the
massaging cosmetic, and the massaging is done during or after
bathing, or during or after exercise.
Specific embodiments of the second beauty-treatment method include
a beauty-treatment method in which, particularly when the face is
the massaging location, massaging is first done in such a way as to
(a) describe a line from the mouth past the wings of the nose,
followed by any of (b) massaging of the cheeks so as to describe a
circle from the mouth, past the lower eyelids, toward the ears, (c)
massaging of the forehead so as to describe an arc from between the
eyebrows past the upper forehead toward either end, and (d)
massaging of the lower eyelids from the inner corners of the eyes
to the outer corners of the eyes; or a beauty-treatment method in
which the massaging in (b), (c) and (d) is done in any sequence
after the massaging in (a). Of these, a preferred beauty-treatment
method for the face is a beauty-treatment method in which (a)
massaging so as to describe a line from the mouth past the wings of
the nose, (b) massaging of the cheeks so as to describe a circle
from the mouth, past the lower eyelids, toward the ears, and (c)
massaging of the forehead so as to describe an arc from between the
eyebrows past the upper forehead toward either end are done, two to
three times each, in the sequence (a), (b) and (c), two to three
times in succession, and (d) massaging of the lower eyelids is then
done from the inner corners of the eyes to the outer corners of the
eyes two to three times.
In the second beauty-treatment method pertaining to the present
invention, a cosmetic comprising disintegrating particles is used
during the massage, but a cosmetic comprising a blood circulation
promoter, oil, cosmetic whitener, or sebum secretion inhibitor is
also used as needed.
Also offered are methods of promoting blood circulation, improving
skin color, alleviating swelling, preventing and eradicating
pimples, preventing cosmetic defects, improving skin tightness,
improving skin slackness, and improving make-up application by
massaging with the aforementioned first and second beauty-treatment
methods, as well as a massaging method for such massaging
cosmetology.
To achieve the second of the aforementioned objects, the present
invention provides a cosmetic method which comprises massaging with
the use of a massaging cosmetic comprising disintegrating particles
before a skincare cosmetic is used after the skin is washed with a
detergent, in cases where the skin is washed with a detergent and a
skincare cosmetic is then used.
The present invention also provides a cosmetic method which
comprises massaging with the use of a massaging cosmetic comprising
disintegrating particles before the skin is washed with a detergent
after it is washed with a cleanser, or massaging with the use of a
massaging cosmetic comprising disintegrating particles before the
skincare cosmetic is used after the skin is washed with the
detergent, in cases where the skin is washed with a cleanser and a
detergent, in that sequence, and a skin care cosmetic is then
used.
A specific method of massaging in the course of the cosmetic method
pertaining to the present invention, particularly when the face is
the massaging location, is a massaging method in which massaging is
first done in such a way as to (a) describe a line from the mouth
past the wings of the nose, followed by any of (b) massaging of the
cheeks so as to describe a circle from the mouth, past the lower
eyelids, toward the ears, (c) massaging of the forehead so as to
describe an arc from between the eyebrows past the upper forehead
toward either end, and (d) massaging of the lower eyelids from the
inner corners of the eyes to the outer corners of the eyes; or a
beauty-treatment method in which the massaging in (b), (c) and (d)
is done in any sequence after the massaging in (a). Of these, a
preferred beauty-treatment method for the face is a
beauty-treatment method in which (a) massaging so as to describe a
line from the mouth past the wings of the nose, (b) massaging of
the cheeks so as to describe a circle from the mouth, past the
lower eyelids, toward the ears, and (c) massaging of the forehead
so as to describe an arc from between the eyebrows past the upper
forehead toward either end are done, two to three times each, in
the sequence (a), (b) and (c), two to three times in succession,
and (d) massaging of the lower eyelids is then done from the inner
corners of the eyes to the outer corners of the eyes two to three
times.
In another embodiment of the cosmetic method pertaining to the
present invention, a cosmetic comprising disintegrating particles
is used during the massage, but a cosmetic comprising a blood
circulation promoter, oil, cosmetic whitener, or sebum secretion
inhibitor is also used as needed.
Also offered are methods of promoting blood circulation, improving
skin color, alleviating swelling, preventing and eradicating
pimples, preventing cosmetic defects, improving skin tightness,
improving skin slackness, and improving make-up application by a
cosmetic method using such massaging.
In the beauty-treatment method of the present invention for
achieving the aforementioned first object, massaging is done in the
direction in which the blood flows, and thus does not run counter
to the direction of the muscle fibers. It therefore does not cause
wrinkles or slackness, even when done by ordinary people who are
not experts. The beauty-treatment method pertaining to the present
invention not only features simply massaging in the direction in
which the blood flows, but also features massaging first in the
direction of arterial blood flow and then in the direction of
venous blood flow, allowing considerable massage-based cosmetic
effects to be obtained in a short period of massaging. For example,
considerable massage-based cosmetic effects can be obtained by
massaging about 30 seconds once a day continuously for about 3 to 6
weeks.
In the beauty-treatment method pertaining to the present invention,
massaging when the pulse, dermal vasculature, skin temperature, or
dermal blood flow is in a stimulated, dilated, elevated, or
stimulated state as opposed to a resting state, or during or after
bathing or exercise, results in greater massaging effects, and thus
greater cosmetic effects, than when massaging is done in a resting
state.
Implementing the beauty-treatment method pertaining to the present
invention while using a cosmetic, particularly a cosmetic
comprising disintegrating particles, on the skin allows even
greater massaging effects to be obtained, while massages featuring
the use of a cosmetic in which a blood circulation promoter, oil,
cosmetic whitener, or sebum secretion inhibitor or the like has
been blended as needed allow the effects of such components to be
greatly enhanced. That is, when a cosmetic comprising
disintegrating particles is used for massaging, the disintegrating
particles gradually disintegrate during the massage, and the
disintegrated particles penetrate into the scale-like protrusions
and depressions of the skin surface, physically stimulating the
skin depending on the particle size at that time. Here, when the
cosmetic contains a blood circulation promoter, the blood
circulation promoter smoothly penetrates into the skin, actively
improving the peripheral circulatory system. The dermal blood flow
is significantly improved by the synergistic effect of the physical
and pharmacological effects of the disintegrating particles in
promoting blood circulation. This prevents skin color blotching,
darkness, dullness, and the like caused by poor blood circulation,
and also dramatically improves skin color. These additional effects
are also more evident when oils, cosmetic whiteners, or sebum
secretion inhibitors are added to the cosmetic.
In the cosmetic method of the present invention for achieving the
second of the aforementioned objects, meanwhile, the massaging is
done before a skincare cosmetic is used after the skin is washed
with a cleanser or detergent, so the skincare cosmetic is used
while the blood circulation is in a significantly promoted state.
This allows the skincare cosmetic to have more effective action,
and can increase the moisture retention function of the corneal
layer of the skin, promote better regeneration of the moist
components of the skin, improve skin softness, improve tightness or
slackness, and improve make-up application.
Particularly when the skin is washed with a cleanser and a
detergent, in that order, and a skincare cosmetic is then used,
massaging between the washing with the cleanser and washing with
the detergent can provide the effect of promoting the restoration
of the skin functions (such as the moisture retention function of
the corneal layer, the function of regenerating the moist
components of the skin, and skin softness) which are lost due to
the cleanser as well as the effect of retaining the dermal function
against washing with detergents. Massaging before a skincare
cosmetic is used after washing with a detergent can also provide
the effect of promoting restoration of skin function lost as a
result of washing with a detergent.
A massaging cosmetic comprising disintegrating particles is used
during the massage in the cosmetic method pertaining to the present
invention, allowing greater massaging effects to be obtained in the
same manner as in the massaging in the aforementioned
beauty-treatment method. Massaging with the use of a cosmetic in
which a blood circulation promoter, oil, cosmetic whitener, or
sebum secretion inhibitor or the like has been blended as needed
allows the effects of these components to be greatly enhanced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
The first and second beauty-treatment methods pertaining to the
present invention as well as the cosmetic method pertaining to the
present invention are described in sequence below.
In the first beauty-treatment method pertaining to the present
invention, any location on the body or face may serve as the object
of the massage. Whatever the location of the massage, the massaging
location is basically first massaged in the direction of arterial
blood flow and then in the direction of venous blood flow. In this
case, the massaging location may be repeatedly massaged in the
direction of arterial or venous blood flow, as long as massaging in
the direction of arterial blood flow precedes massaging in the
direction of venous blood flow. Alternatively, the entire massaging
location may be massaged in the direction of arterial blood flow,
and then any portion in the massaged location may be massaged in
just the direction of venous blood flow. Again alternatively, the
area may be again massaged in the direction of arterial blood flow
and then massaged in the direction of venous blood flow.
For example, when the face is massaged, as shown in FIG. 1,
massaging is first done (a) in the direction of facial arterial
blood flow so as to describe a line from the mouth past the wings
of the nose. Massaging is then done as needed in the direction of
arterial blood flow where the facial arteries branch out, and then
in the direction of the blood flow of the facial veins or
superficial temporal veins or the veins draining therein. That is,
(b) the cheeks are massaged in the direction of the blood flow of
the arteria angularis and then in the direction of the blood flow
of the superficial temporal veins, so as to describe a circle from
the mouth past the lower eyelids toward the ears, or (c) the
forehead is massaged in the direction of the blood flow of the
supraorbital arteries and then in the direction of the blood flow
of the superficial temporal vein, so as to describe an arc from
between the eyebrows past the upper forehead toward either end, or
(d) the lower eyelids are massaged in the direction of the inferior
ophthalmic vein and superficial temporal veins, from the inner
corners of the eyes to the outer corners of the eyes.
Alternatively, the massaging in (b), (c) and (d) is done in any
sequence following the massaging in (a).
As a particularly desirable method among these cosmetic massaging
methods, the massaging in (a) is done two to three times, the
massaging in (b) and (c) is then done, in that sequence, two to
three times, and the massaging in (d) is then done two to three
times. In this case, the massaging in (a) through (d) is completed
in about 20 to 60 seconds.
When a location other than the face, such as the body, is massaged,
as shown in FIG. 2, centrifugal massaging is done from the heart
along the arterial system or from the brain or spine along the
nervous system, and then, as shown in FIG. 3, centripetally from
the peripheral regions along the venous or lymphatic system.
In the present invention, massaging should be managed with the
palms of the hands or the balls of fingers, preferably all ball of
fingers, so as to slide over the skin in the massaging
location.
A cosmetic is also preferably applied to the skin before the
massage. Examples of cosmetics which can be used in such cases
include a variety of massaging cosmetics such as massaging cremes
and massaging oils, but should in particular include disintegrating
particles.
Here, a variety of particles can be used as the disintegrating
particles as long as they disintegrate as a result of heat, the
action of water, or the friction when the cosmetic is applied to
the skin. Examples include disintegrating granules obtained by the
granulation of primary particles, and disintegrating microcapsules
which disintegrate as a result of shear.
Examples of disintegrating granules which can be used include those
consisting of water-insoluble primary particles and a binder. Here,
examples of water-insoluble primary particles which can be used in
the manufacture of disintegrating granules include polyethylene,
polystyrene, polyester, polyvinyl chloride, polyamides,
polypropylene, nylon, polyvinylidene fluoride, polyurethane,
acrylic resins, polysiloxane, crystalline cellulose, starch, and
organic polymer compounds of derivatives of these, or silica,
alumina, talc, kaolin, titanium oxide, zinc oxide, quartz, calcium
phosphate and other such inorganic powders or the like.
The primary particles may have any configuration such as spherical
or amorphous configurations, but a spherical configuration is
particularly preferred for the sake of safety. The average particle
diameter of the primary particles is 1 to 20 .mu.m, and preferably
3 to 15 .mu.m. In consideration of eye safety, at least 80 wt %
should be no more than 10 .mu.m, and preferably between 4 and 10
.mu.m.
During the manufacture of the disintegrating granules, a binder
binds the aforementioned water-insoluble primary particles so as to
form disintegrating granules. In this case, the bonding strength of
the primary particles as a result of the binder is enough for the
disintegrating granules to be readily dissolved on the skin by
massaging or by friction. Specific examples of binders include fish
oil, hardened castor oil, hardened rapeseed oil and other such
animal and vegetable oils that are solid at ordinary temperature,
ethylcellulose, acetylcellulose, nitrocellulose,
hydroxymethylcellulose, hydroxyethylcellulose,
hydroxypropylcellulose, polyvinyl pyrrolidone, vinyl acetate and
other such organic polymer compounds.
Disintegrating granules consisting of such primary particles and
binders can be formed, for example, by common methods of
granulation such as fluidized bed granulation, agitated
granulation, and extrusion granulation, and in particular the
method (Japanese Laid-Open Patent Application 60-152407) in which
the primary particles are dispersed in a water-insoluble binder,
and the solvent is evaporated off, or the method (Japanese
Laid-Open Patent Application 6-271417) in which a water-insoluble
binder powder is mixed with primary particle granules, then
granulated with a water-soluble binder, then heated to melt the
water-insoluble binder powder, and cooled so as to increase the
water resistance of the granules.
The particle size of the disintegrating granules thus formed is
preferably 100 to 1000 .mu.m, and even more preferably 200 to 600
.mu.m. A particle size of less than 100 .mu.m results in poor
massaging effects, and fails to provide the pronounced effects in
improving skin color or the effects in promoting blood circulation
associated with the massage. A particle size of more than 1000
.mu.m results in rough feeling and in initial stimulation too
intense when rubbed into the skin.
Examples of disintegrating microcapsules which can be used include
those manufactured in Japanese Laid-Open Patent Applications
59-78510, 61-282306, 1-125313 and 5-92909. Examples of capsule
materials for disintegrating microcapsules include gelatin, sodium
alginate, propylene alginate glycol esters, polyacrylic acid,
polymethacrylic acid, methyl polyacrylate esters, ethyl
polyacrylate esters, butyl polyacrylate esters, methyl
polymethacrylate esters, ethyl polymethacrylate esters, butyl
polymethacrylate esters, gum arabic, carboxymethylcellulose,
hydroxyethylcellulose, methylcellulose, sodium polyacrylate,
carboxyvinyl polymers, polyvinyl alcohols, polyacrylamides,
polyvinyl pyrrolidone, ethylene polyoxide, casein, pectin,
polyacrylonitrile, polyvinyl acetate, polyvinyl ether, polystyrene,
agar, carrageenan, corn starch, gluten, dextrin, guar gum, locust
bean gum, polyvinyl chloride, polyvinylidene chloride,
polyethylene, polyethylene glycol dimethacrylate, polydivinyl
benzene, polypropylene, polybutadiene and other such polymer
compounds, either individually or in mixtures of two or more, or
copolymers incorporating two or more monomers constituting the
aforementioned polymers.
Examples of materials encapsulated in the microcapsules include the
blood circulation promoters, oils, cosmetic whiteners, sebum
secretion inhibitors, humectants, softeners, colorants, perfumes
and solvents described below.
The particle size of the disintegrating capsules is preferably 100
to 1000 .mu.m, and even more preferably 200 to 600 .mu.m, in the
same manner as the aforementioned disintegrating granules.
The particle size of the disintegrating particles such as
disintegrating granules or disintegrating microcapsules in the
present invention is the average particle diameter obtained by
measurement using the light scattering method, light diffraction
method, or the like.
In the first beauty-treatment method pertaining to the present
invention, when massaging is done using a cosmetic containing the
aforementioned disintegrating particles, the time for the massage
should be the time during which the cosmetic is applied to the
prescribed massaging location, the prescribed location is lightly
massaged with the palms of the hands or the balls of the fingers,
preferably all four fingers with the exception of the thumb, and
the disintegrating particles are no longer felt. This time is
usually about 20 to 60 seconds.
The cosmetic effects achieved by the first beauty-treatment method
pertaining to the present invention include, specifically, effects
in promoting blood circulation and various resulting effects, such
as effects in improving skin color by eliminating color blotches or
darkness and enhancing luster or transparency, effects in
eliminating swelling, effects in preventing or reducing pimples,
effects in preventing cosmetic defects, effects in improving skin
tightness or slackness, and effects in improving make-up
application. These effects can be even further enhanced by using
cosmetics containing the aforementioned disintegrating particles
during the massage. A variety of other additives can also be
blended in the cosmetic containing the disintegrating particles
according to the specific purpose of the massage in the present
invention, including promoting blood circulation, improving skin
color, reducing swelling, preventing and eradicating pimples,
preventing cosmetic defects, improving skin tightness, improving
skin slackness, or improving cosmetic application. The components
blended in the cosmetic and the proportion in which the components
are blended can be determined as desired.
For example, when attempting to obtain greater effects in improving
skin color through massaging, the aforementioned disintegrating
particles should be blended in an amount of 0.1 to 5 wt %, and more
preferably 0.5 to 3 wt %, in the cosmetic. Less than 0.1 wt %
results in poor skin color improving effects, whereas more than 5
wt % results in discomfort at the beginning of the massage.
A blood circulation promoter should be included to obtain greater
skin color improving effects with the massage. Various well-known
substances having an effect in promoting blood circulation can be
used as the blood circulation promoter, examples of which include
the vasodilator Vitamin E esters, nicotinic acid esters or orotic
acid esters disclosed in Japanese Laid-Open Patent Application
62-87506, or the peripheral circulation promoter Vitamin E esters,
acetic acid esters or succinic acid esters disclosed in Japanese
Laid-Open Patent Application 62-195316. Nicotinic acid amides,
methyl nicotinate, and the like can also be used. Examples of
vegetable extracts include those disclosed as having blood
circulation promoting effects in the Fragrance Journal, special
issues No. 6 (1986) and No. 1 (1979), such as extracts of arnica,
crataegus, cinchona bark, Salvia officinalis, Tilia miqueliana,

common fennel, prickly mountain ash, peony root, eucalyptus,
mugwort, Isodon japanicus, rice, Sophora flavescens, ginger and
clove.
Of these, those that are preferred for their effects in promoting
blood circulation include tocopherol nicotinate, tocopherol acetate
and nicotinic acid amide, while preferred vegetable extracts
include swertia herb extract, Hypericum erectum extract, ginkgo
extract, arnica extract, witch-hazel extract, marigold extract,
marronnier extract, Isodon japanicus extract, Salvia officinalis
extract, glehnia root extract, rice germ oil and Tilia miqueliana
extract, of which tocopherol nicotinate and marronnier extract are
particularly desirable.
These blood circulation promoters can be used individually or in
combinations of two or more, and are usually used in an amount of
0.001 to 5 wt %, and preferably 0.01 to 3 wt %, of the
cosmetic.
Oils that make the skin lustrous, cosmetic whiteners that improve
spots, freckles, darkness and the like associated with melanin, and
sebum secretion inhibitors having effects such as the inhibition of
melanin deposition in hair follicles should be simultaneously
blended with the disintegrating particles, because the additional
effects can be further intensified.
Here, oils that make the skin lustrous should have a refractive
index of at least 1.444 or an SP value of at least 16.5 in the
interests of suppressing light scattering and reflection, making
the skin lustrous, and eliminating skin color blotching. Here, the
SP value is a dissolution parameter calculated from the organic and
inorganic properties.
Examples of oils meeting such conditions, with a refractive index
of at least 1.444, include isotridecyl isononate, glycerol

When a cosmetic is used for massaging in the first beauty-treatment
method pertaining to the present invention, cosmetics consisting of
the aforementioned components may be in either liquid or solid
form, but are preferably used as liquids in containers from which
they are discharged in constant amounts. This allows suitable
constant amounts to be discharged by a simple operation during the
massage. Here, a liquid state includes any of cremes, pastes, gels,
O/W emulsions and W/O emulsions. Here, the diameter of narrowest
conduit of the container used to discharge constant amounts of the
cosmetic must be greater than the particle diameter of the
disintegrating particles contained in the liquid cosmetic, in order
to prevent the container from closing up and poor discharging of
cosmetic. The type of such a container for discharging constant
amounts is not particularly limited, and examples include pump
containers and metering containers.
Of these, pump containers have a pump chamber consisting of a
cylinder and piston, where the vertical operation of the piston
discharges a constant amount of the determined cosmetic depending
on the volume of the pump chamber. There are various types of pump
containers, which can be widely used in the present invention.
In the second beauty-treatment method pertaining to the present
invention, massaging is done when the pulse, dermal vasculature,
skin temperature, or dermal blood flow is in a stimulated, dilated,
elevated, or stimulated state as opposed to a resting state in
order to enhance the cosmetic effects obtained by the massage.
Because of individual variation in the resting pulse, dermal
vasculature, skin temperature, and dermal blood flow state, in the
present invention a pulse in a stimulated state as opposed to a
resting state is determined on the basis of the resting state of
the individual receiving the massage. The pulse is usually 60 to
100 beats/min in a resting state, the skin temperature is 33 to
35.degree. C., and the dermal blood flow is 30 to 150 mL/min/100 g,
so a level beyond these levels is considered a stimulated state in
the present invention. The ratio between the vascular thickness and
inside diameter are reduced when the vessels dilate, so a dilated
dermal vascular state can be determined on the basis of the value
for the "vascular thickness"/"vascular inside diameter." In the
capillaries, for example, a value of vascular thickness/vascular
inside diameter.ltoreq.1/5 can usually be defined as a stimulated
state.
In the second beauty-treatment method pertaining to the present
invention, massaging is done when at leastightness of the pulse,
dermal vasculature, skin temperature, or dermal blood flow is in a
stimulated state as opposed to a resting state. The pulse or the
like is in a stimulated state during or after bathing or exercising
in terms of actual activity. The present invention thus includes
massaging during or after bathing or exercising.
In the second beauty-treatment method pertaining to the present
invention, the object of massaging is any location on the body and
face, just as in the first beauty-treatment method pertaining to
the present invention. Although the direction of the massage, the
number of times the massaging is done, the sequence of the
massaging locations, and the like are not particularly limited, all
locations are preferably massaged in accordance with the
aforementioned massaging method in the first beauty-treatment
method of the present invention.
In the second beauty-treatment method pertaining to the present
invention, various massaging cosmetics such as massaging cremes and
massaging oils can be used on the skin in advance during the
massage, although cosmetics including disintegrating particles are
used in particular. Here, the aforementioned disintegrating
particles or cosmetics containing disintegrating particles can be
used, allowing the aforementioned massaging effects to be
obtained.
In the second beauty-treatment method pertaining to the present
invention, when massaging is done using a cosmetic containing the
aforementioned disintegrating particles, the time for the massage
should be the time during which the cosmetic is applied to the
prescribed massaging location, the prescribed location is lightly
massaged with the palms of the hands or the balls of the fingers,
preferably all four balls of the fingers with the exception of the
thumb, and the disintegrating particles are no longer felt, in the
same manner as in the first beauty-treatment method of the present
invention. This time is usually about 20 to 60 seconds.
The cosmetic effects achieved by the second beauty-treatment method
pertaining to the present invention include, specifically, effects
in promoting blood circulation and various resulting effects, such
as effects in improving skin color by eliminating color blotches or
darkness and enhancing luster or transparency, effects in
eliminating swelling, effects in preventing or reducing pimples,
effects in preventing cosmetic defects, effects in improving skin
tightness or slackness, and effects in improving make-up
application. A variety of additives can also be blended in the
cosmetic used in the massage according to the specific purpose of
the massage in the present invention, including promoting blood
circulation, improving skin color, reducing swelling, preventing
and eradicating pimples, preventing cosmetic defects, improving
skin tightness, improving skin slackness, or improving cosmetic
application. The components blended in the cosmetic and the
proportion in which the components are blended can be determined as
desired, preferably in accordance with the aforementioned first
beauty-treatment method.
In the second beauty-treatment method pertaining to the present
invention, the cosmetics that are used may be in either liquid or
solid form, but are preferably used as liquids in containers from
which they are discharged in constant amounts, just as in the first
beauty-treatment method.
When the skin is washed with a detergent and a skincare cosmetic is
then used in the cosmetic method pertaining to the present
invention, massaging is done with the use of a massaging cosmetic
comprising disintegrating particles before the skincare cosmetic is
used after the skin is washed with a detergent. When the skin is
washed with a cleanser and a detergent, in that sequence, and a
skincare cosmetic is then used, massaging is done with the use of a
massaging cosmetic comprising disintegrating particles before the
skin is washed with a detergent after it is washed with a cleanser,
or massaging is done with the use of a massaging cosmetic
comprising disintegrating particles before the skincare cosmetic is
used after the skin is washed with the detergent.
Here, examples of cleansers used to wash the skin include various
conventional types which wash off the oily soil of foundations and
the like, such as emulsions, skin lotions, oils, or gels which
contain a primary component such as liquid paraffin, squalane,
Vaseline, beeswax, cetanol, stearic acid, cetyl alcohol, propylene
glycol or glycerol.
Examples of detergents include various conventional types used to
clean away sebum, perspiration and dirt. Examples include weakly
alkaline cosmetic soaps consisting primarily of fatty acid alkali
salts, as well as weakly alkaline tightnessutral cleansing foams,
body shampoos and hand soaps consisting primarily of surfactants
such as monoalkyl phosphates, sodium acylglutamates, fatty acid
alkylol amides and amine oxides.
Examples of skincare cosmetics used after the skin has been washed
include conventionally used skincare cosmetics such as skin
lotions, emulsion and cremes. Because the absorption of
moisturizing components is promoted when the skin is softened, the
use of a skin lotion followed by the use of an emulsion or creme is
particularly preferred.
Examples of skin lotions that can be used here include moisturizing
skin lotions, astringent skin lotions and softener skin lotions.
Examples of emulsions which can be used include emollient lotions,
nourishing lotions, moisture lotions and milky lotions. Examples of
cremes which can be used include emollient cremes, nourishing
cremes, base cremes, cold cremes and moisture cremes.
In the cosmetic method pertaining to the present invention,
massaging is done before the use of the skincare cosmetic after the
skin has been washed with a cleanser or detergent. Such a cosmetic
method can be applied to any location on the body and face.
Accordingly, any location on the body and face may serve as an
object of massaging done in the course of the cosmetic method
pertaining to the present invention.
Although the direction of the massage, the number of times the
massaging is done, the sequence of the massaging locations, and the
like are not particularly limited in the massaging method, all
locations are preferably massaged in accordance with the
aforementioned massaging method in the first beauty-treatment
method of the present invention.
A cosmetic containing disintegrating particles is used as a
massaging cosmetic during the massage in the cosmetic method
pertaining to the present invention. Here, the aforementioned
disintegrating particles or cosmetics containing disintegrating
particles noted in the first beauty-treatment method of the present
invention can be used, allowing the aforementioned massaging
effects to be obtained, just as in the second beauty-treatment
method of the present invention.
In the cosmetic method pertaining to the present invention, when
massaging is done using a cosmetic containing the aforementioned
disintegrating particles, the time for the massage should be the
time during which the cosmetic is applied to the prescribed
massaging location, the prescribed location is lightly massaged
with the palms of the hands or the balls of the fingers, preferably
all four balls of the fingers with the exception of the thumb, and
the disintegrating particles are no longer felt, in the same manner
as in the first and second beauty-treatment methods of the present
invention. This time is usually about 20 to 60 seconds.
In the beauty-treatment method of the present invention, massaging
with the use of the aforementioned massaging cosmetics, or the use
of a skincare cosmetic following such massaging, can increase the
moisture retention function of the corneal layer, and can promote
blood circulation and thus rapidly restore moist components of the
skin, as well as various other effects associated with the effects
in promoting blood circulation, such as effects in improving skin
tightness or slackness, effects in improving cosmetic application,
effects in preventing cosmetic defects, effects in improving skin
color by eliminating color blotches or darkness and enhancing
luster or transparency, effects in eliminating swelling, and
effects in preventing or reducing pimples. These effects can be
even further enhanced by blending various additives in the
massaging cosmetic containing the disintegrating particles as
needed. The components blended in the massaging cosmetic and the
proportion in which the components are blended can be determined as
desired, but are preferably managed in the same manner as in the
aforementioned first beauty-treatment method.
The configuration of the massaging cosmetics that are used in the
cosmetic method of the present invention may be the same as in the
aforementioned first and second beauty-treatment methods, and they
are preferably used as liquids in containers from which they are
discharged in constant amounts.
TEST EXAMPLES
The present invention is described in greater detail below with
reference to test examples.
Test Example 1
Twenty normal females in their forties were divided into two
groups, cosmetics having the composition in Table 1 were used as
the massaging cosmetic, and methods A (Test Example 1-1) and B
(Test Example 1-2) were completed once in 30 seconds, once a day
for six weeks in the bathroom in the following manner for each
group. The dermal blood flow, darkness index, and tightness index
were compared in the following manner before and six weeks after
massaging was begun with these methods. The results are given in
FIGS. 4 through 6.
TABLE 1 Massaging cosmetic (wt %) purified water 89.9
disintegrating granules (*1) 1.0 blood circulation promoter:
nicotinic acid-d1-.alpha.-tocopherol 1.0 polyoxyethylene hardened
castor oil 1.0 carboxyvinyl polymer 0.5 3% water-soluble collagen

(*1) Prepared in accordance with the method noted in Japanese
Laid-Open Patent Application 6-271414 using disintegrating
granules: 91 wt % polyethylene powder as primary particles (mean
particle diameter: 5 .mu.m), 3 wt % hardened rapeseed oil as the
binder, and 6 wt % hydroxypropylcellulose.
Method A (Test Example 1-1)
(A-1) Approximately 2 mL cosmetic was placed in the palm of the
hand and applied over the entire face.
(A-2) All four fingers of both hands (index finger through pinky)
were used to massage two to three times so as to describe a line
from the mouth past the wings of the nose (see direction (a) in
FIG. 1).
(A-3) Massaging was done two to three times so as to describe a
circle from the center of the cheeks to the outside (see direction
(b) in FIG. 1).
(A-4) Massaging was done two to three times so as to describe an
arc from the center of the forehead to the outside (see direction
(c) in FIG. 1).
(A-5) (A-2) through (A-4) were repeated three times.
(A-6) The area under the eyes was massaged toward the outside three
times so as to describe a gradual arc (see direction (d) in FIG.
1).
(A-7) Washed with lukewarm water.
Method B (Test Example 1-2)
(B-1) Approximately 2 mL cosmetic was placed in the palm of the
hand and applied over the entire face.
(B-2) All four fingers of both hands (index finger through pinky)
were used to massage two to three times so as to describe a line
from the wings of the nose past the mouth (direction opposite
A-2).
(B-3) Massaging was done two to three times so as to describe a
circle from the outside of the cheeks to the center (direction
opposite A-3).
(B-4) Massaging was done two to three times so as to describe an
arc from the outside of the forehead to the center (direction
opposite A-4).
(B-5) (B-2) through (B-4) were repeated three times.
(B-6) The area under the eyes was massaged toward the inner three
times so as to describe a gradual arc (direction opposite A-6).
(B-7) The areas were washed with lukewarm water.
Here, the dermal blood flow was measured with a laser tissue blood
flow meter.
For the darkness index, dark to light skin color was divided into
ten ranks from 1 to 10 by five experts, and the mean value was used
as the darkness index.
For the tightness index, "not tight" to "tight" states were divided
into ten ranks from 1 to 10, and the mean value was used as the
tightness index.
The results of FIGS. 4 through 6 confirmed that the
beauty-treatment method of the present invention, in which
massaging was first done in the direction of arterial blood flow
and then in the direction of venous blood flow, afforded better
cosmetic effects in terms of dermal blood flow, darkness, and
tightness than did the beauty-treatment method of the comparative
example in which massaging was done in the opposite direction.
Test Example 2
The same method A as that in Test Example 1-1 was carried out using
the same composition as in Table 1 as the massaging cosmetic,
except that it contained no disintegrating granules or blood
circulation promoter, and the dermal blood flow, darkness index,
and tightness index were evaluated before and six weeks after
massaging was begun (Test Example 2-1).
A cosmetic containing no disintegrating particles or blood
circulation promoter was used in the same manner as in Test Example
2-1, except that conventional beauty-treatment methods C (Test
Example 2-2) and D (Test Example 2-3) below were carried out, and
the dermal blood flow, darkness index, and tightness index were
evaluated before and six weeks after massaging was begun. The
results are given in FIGS. 7 through 9. These figures combine the
results of Test Example 1-1 above for reference.
Method C (Test Example 2-2)
(C-1) Approximately 2 mL cosmetic was placed in the palm of the
hand and applied over the entire face.
(C-2) The forehead was massaged three times from bottom to top by
alternately rubbing with both hands, as shown by (a) in FIG.
19.
(C-3) Massaging was done three times so as to describe a spiral
from between the eyebrows to the outside as shown by (b).
(C-4) Massaging was done by lightly moving the fingertips three
times up from the bottom at the sides of the nose as shown by
(c).
(C-5) Massaging was done three times by rubbing around the mouth so
as to raise the corners of the mouth as shown by (d).
(C-6) Massaging was done twice by spirally rubbing the cheeks in
three stages (top, middle, bottom) as shown by (e).
(C-7) Massaging once around the eyes was done three times as shown
by (f).
(C-1) through (C-7) above were done for about 3 to 5 minutes.
Method C is a method in which massaging is done centripetally from
a location distant from the heart to a location that is near. This
method involves massaging along the vascular distribution, but not
along the flow of blood.
Method D (Test Example 2-3)
(D-1) Approximately 2 mL cosmetic was placed in the palm of the
hand and applied over the entire face.
(D-2) Massaging was done three times by alternately rubbing the
sides from the center of the neck with the palms of both hands,
from the bottom toward the top, as shown by (a) in FIG. 20.
(D-3) Massaging was done three times by placing the index fingers
of both hands in the center of the chin and underpart of the lips,
and placing the middle finger of both hands in the lower part of
the chin, rubbing the index fingers and the middle fingers
alternately left and right on the mandible as far as the bottom of
the ears as shown by (b).
(D-4) The middle and ring fingers of both hands were placed on the
chin, massaging was done so as to describe a spiral toward both
ends of the lips, and massaging was further done three times by
rubbing toward the top of the lips as shown by (c).
(D-5) Both sides of the wings of the nose were massaged three times
from top to bottom with the middle and ring fingers of both hands
as shown by (d).
(D-6) Massaging was done three times by rubbing up from the tip of
the nose as shown by (e).
(D-7) Massaging was done three times each by rubbing from the sides
of the lips and the sides of the wings of the nose or center of the
nose toward the temples using the middle and ring fingers as shown
by (f).
(D-8) Massaging was done three times each by rubbing from the sides
of the lips and the sides of the wings of the nose or center of the
nose toward the temples so as to describe a spiral as shown by
(g).
(D-9) The cheeks were patted three times in their entirety using
all fingers of both hands.
(D-10) The middle and ring fingers were placed on the upper
eyelids, and the fingers were gently rubbed while exerting pressure
from the inner corners of the eyes toward the outer corners of the
eyes as shown by (h).
(D-11) Massaging was done three times by rubbing the entire
forehead with the fingertips perpendicularly from the bottom
upwards as shown by (i).
(D-1) through (D-11) were done for about 3 to 5 minutes.
Method D is a method in which massaging is done centrifugally from
the heart. In this method, the supply of blood from the heart to
the dermal tissue is considered, whereas the blood from the dermal
tissue to the heart is not considered.
The results of FIGS. 7 through 9 confirmed that, even without the
use of a massaging cosmetic containing disintegrating particles,
the beauty-treatment method of the present invention, in which
massaging was first done in the direction of arterial blood flow
and then in the direction of venous blood flow, afforded better
cosmetic effects in terms of dermal blood flow, darkness, and
tightness than did the conventional beauty-treatment method in
which the direction of the blood circulation was not taken into
account.
Test Example 3
Thirty normal females in their forties were divided into three
groups A through C, and a beauty-treatment method consisting of the
massage in method A of Test Example 1-1 was done once for 30
seconds in each group using a cosmetic having the composition in
Table 1 above. This was done once a day for six weeks while the
subjects were in a resting state before washing their faces upon
rising in the morning in Group A (Test Example 3-1), while the
subjects were bathing in Group B (Test Example 3-2), and after the
subjects had jogged 3 km for 20 minutes in Group C (Test Example
3-3).
Here, the pulse and skin temperature were measured when the massage
was begun, that is, during the actual massage, in each group. The
results are given in Table 2.
The dermal blood flow, darkness index, and tightness index were
determined and compared as shown below before and six weeks after
massaging was begun in the same way as Test Example 1. The results
are given in FIGS. 10 through 12.

Table 2 shows that stimulated pulse and skin temperature were in
the following order: Group C>Group B>Group A. The results in
FIGS. 10 through 12 show the effects of stimulated dermal blood
flow as a result of massage, the effects of less darkness, and the
effects of improvement in tightness in the following order: Group
C>Group B>Group A. It could thus be confirmed that better
cosmetic effects from massaging were obtained when the pulse or the
like was stimulated.
Test Example 4
The same massaging as that described above was done in Groups A
(Test Example 4-1), B (Test Example 4-2), and C (Test Example 4-3)
using a cosmetic having the same composition as that in Table 1 as
the massaging cosmetic except that it contained no disintegrating
particles or blood circulation promoters, and the dermal blood
flow, darkness index, and tightness index were evaluated before and
six weeks after massaging was begun. The results are given in FIGS.
13 through 15.
FIGS. 13 through 15 show that, when the massaging cosmetic
including no disintegrating particles or blood circulation
promoters were used, the effects of stimulated dermal blood flow,
the effects of less darkness, and the effects of improvement in
tightness were in the following order: Group C>Group B>Group
A, which was the same order as the stimulated pulse and the like
during massage, and that better cosmetic effects from massaging
were obtained in groups C and B, which had stimulated pulse levels
and the like during massage, than when at rest in group A. However,
the cosmetic effects resulting from the massage did not improve as
much as in the aforementioned Test Examples 3-3 and 3-2, where
cosmetics containing disintegrating particles and blood circulation
promoters were used. It may thus be seen that the use of cosmetics
containing disintegrating particles and blood circulation promoters
as a massaging cosmetic is preferred.
Test Example 5
Twenty normal females in their thirties were divided into two
groups A and B, a cosmetic method consisting of the following
cosmetic step A (Test Example 5-1) or B (Test example 5-2) was used
on skin where foundation had been applied, and the (i) corneal
layer moisture content, (ii) amount of sebum restoration, and (iii)
feeling of stiffening were evaluated as follows. The results are
given in FIGS. 16 through 18.
Cosmetic Step A (Test Example 5-1)
(A-1) Cleansing: 2 g cosmetic having the composition shown in Table
3 was used as a cleansing cosmetic, this was applied over the
entire face, and it was washed off with water.
TABLE 3 Cleansing cosmetic (wt %) polyoxyethylene octyl dodecyl
ether (20 E.O.) (ELB = 13) 12.5 stearyl trimethylammonium chloride

(A-2) Massage: The massage in method A of Test Example 1-1 was done
for 30 seconds using the aforementioned massaging cosmetic having
the composition in Table 1 as the massaging cosmetic.
(A-3) Washing face with detergent: 1 mL of the facial detergent
having the composition given in Table 4 was placed in the palm of
the hand, this was applied to the entire face and lathered, and it
was washed off with water.

(A-4) Use of skin lotion: 1 mL of a cosmetic having the composition
given in Table 5 was placed in the palm of the hand as skin lotion,
and it was applied to the entire face.

(A-5) Use of emulsion: 1 mL of a cosmetic as emulsion having the
composition given in Table 6 was placed in the palm of the hand and
applied to the entire face.

Cosmetic Step B (Test Example 5-2)
(A-2) The steps were carried out in sequence in the same manner as
in cosmetic step A except that no massaging was done.
Evaluation Parameters
(i) Corneal Layer Moisture Content
The dermal conductance was determined with a conductance meter as
an index of the corneal layer moisture content.
(ii) Amount of Sebum Restoration
The amount of squalane on the surface of the skin was measured by
gas chromatography as an index of the amount of sebum
restoration.
(iii) Feeling of stiffening
The subjects evaluated "stiffening" to "not stiffening" in five
ranks, the mean for each group was determined, and this was used as
the tightness index.
FIGS. 16 through 18 show that sebum was restored more rapidly, the
corneal layer moisture retention was better, there was no feeling
of stiffening, and there was far greater skincare cosmetic action
when massaging was done with the use of a massaging cosmetic
containing disintegrating particles before the use of skin lotion
and emulsion skincare cosmetics than when a skincare cosmetic was
used without such massaging.
INDUSTRIAL APPLICABILITY
In the first or second beauty-treatment method pertaining to the
present invention, massaging can be readily done even by ordinary
people, and considerable cosmetic effects can be obtained as a
result of the massage. More specifically, a variety of effects can
be obtained, including the promotion of blood circulation, better
skin color, less swelling, the prevention or eradication of
pimples, the prevention of cosmetic defects, better skin tightness,
improvement of slackness, and better cosmetic application. As such,
the beauty-treatment method pertaining to the present invention is
useful as a method of daily skincare.
In the cosmetic method pertaining to the present invention, a
skincare cosmetic is used after washing, allowing more effective
use of the skincare cosmetic to be achieved. It is thus possible to
enhance the moisture retention function of the corneal layer of the
skin, promote regeneration of the moist components of the skin,
improve skin softness, improve tightness or slackness, improve
cosmetic application, and prevent cosmetic defects.
